As he came out of a little gully a few miles up the river and rode along the crest of a ridge that rose above endless miles of plains, his thoughts went back to that first night in the bunkhouse when the outfit had come in from the range. Satisfaction glinted in his eyes.

"I reckon them boys didn't make good with her. An' I expect that some day Leviatt will find he's been wastin' his time."

He frowned at thought of Leviatt and unconsciously his spurs drove hard against the pony's flanks. The little animal sprang forward, tossing his head spiritedly. Ferguson grinned and patted its flank with a remorseful hand.

"Well, now, Mustard," he said, "I wasn't reckonin' on takin' my spite out on you. You don't expect I thought you was Leviatt." And he patted the flank again.

He rode down the long slope of the rise and struck the level, traveling at a slow lope through a shallow washout. The ground was broken and rocky here and the snake-like cactus caught at his stirrup leathers. A rattler warned from the shadow of some sage-brush and, remembering his previous experience, he paused long enough to shoot its head off.

"There," he said, surveying the shattered snake, "I reckon you ain't to blame for me bein' bit by your uncle or cousin, or somethin', but I ain't never goin' to be particular when I see one of your family swingin' their head that suggestive."

He rode on again, reloading his pistol. For a little time he traveled at a brisk pace and then he halted to breathe Mustard. Throwing one leg over the pommel, he turned half way around in the saddle and swept the plains with a casual glance.

He sat erect instantly, focusing his gaze upon a speck that loomed through a dust cloud some miles distant. For a time he watched the speck, his eyes narrowing. Finally he made out the speck to be a man on a pony.

"He's a-fannin' it some," he observed, shading his eyes with his hands; "hittin' up the breeze for fair." He meditated long, a critical smile reaching his lips.

"It's right warm to-day. Not just the kind of an atmosphere that a man ought to be runnin' his horse reckless in." He meditated again.
